Backlighting Makes Flowers Glow

At a university garden, I came across these tulips backlit by the sun. And they grew in front of a deeply shaded background. Manual exposure and spot metering came to my rescue.

1/125 second, f/16, ISO 200, 93mm

I needed quite a bit of depth of field because the flowers were different distances from the camera. With my lens set to 93mm, the depth of focus was further limited. So I set the aperture to f/16.

The flowers were swaying a bit in a gentle breeze, so I selected a shutter speed of 1/125 second to freeze their movement. 

Using the spot meter, I measured the brightness of the tulips alone, without including the background. Because the blooms were yellow and very bright, I needed to increase their exposure from zero to +1. I did not want to change the aperture or the shutter speed, so I increased the ISO from 100 to 200 so the flowers would appear glowing in the final image.
